Before the French Revolution there was an insane amount of chaos and injustice. The church was very powerful and the people had no power. People knew they couldn't do anything about the increasing injustice within their government. Do you think that there were always angry people who wanted to overthrow, or do you think people were always scared until the revolution?
While France's people were starving, literally, the upper class people were striving. The top 3% of people (nobles, clergymen, and royalty) owned a third of all of the land in France. They also paid the least taxes. The system was built for the rich and privelaged. Do you think we have a similarly set up government today? The rich and privelaged are set up to succeed?
All the while, Marie Antoinette was throwing lavish and extravagant parties at her palace. Versialles was center of pure enjoyment. But only for the rich, as 97% of the population couldn't touch versialles with a mile long pole. How do you think that Marie Antoinette thought of the commoners lifestyle?
